Classic Macaroni Salad

This is so totally NOT good-for-you, but it's really yummy in the classic American junk food sense. I think the sugar is the magic ingredient. We had this for dinner tonight, along with hot dogs, baked beans, french fries, and collard greens. Not every night is gourmet around here, that's for sure!

2 cups uncooked elbow macaroni (I prefer the multi-grain kind, like Barilla Plus)
1/2 cup mayonnaise
2 Tbsp white vinegar
1/3 cup white sugar
1 1/4 Tbsp prepared yellow mustard
1 1/4 tsp salt
1/4 tsp black pepper
1 small onion, diced (1/2 cup or less)
2 stalks celery, chopped small
1/2 green pepper, chopped small
2-4 Tbsp grated carrot
2 Tbsp pimiento or stuffed green olives, chopped small

Cook pasta until al dente. Meanwhile, combine all other ingredients in a bowl. When pasta is done, rinse thoroughly with cold water, then stir into sauce.
